3DMark Fire Strike
3DMark is the latest version of this hugely-popular synthetic benchmark. Making use of DX11 features such as tessellation, compute shaders and multi-threading, it provides modern-day results and is available as a free download.
3DMark is our customary starting point and it highlights the Titan Xp predicament perfectly. This is a mighty potent GPU, yet there's no escaping the fact that out-the-box performance is practically identical to a custom-cooled and overclocked GTX 1080 Ti costing hundreds of pounds less.
